Hello, I hope my answer can give you some help. If you are in the gym, I don't recommend you to wear beauty contact lenses, because in the gym, for example, when you are taking a spinning class, your body should bend over and look straight or look up at the coach. In this case, your eyes are a little tired, cosmetic contact lenses will do you some harm, and the intrusion of sweat will also bring inconvenience to many actions such as wiping your eyes.
